The MATE is now ready to program the FX plugged 
into Port 2 of the HUB. 
1-2ph Master is the factory default value for each 
FX.

Pressing                will keep the MATE’s 
attention on Port 2, but will change the stack 
phase to Classic Slave screen. Port 02 will then be 
assigned as a Classic Slave. You can change the 
stacking phase by pressing                or
and change to a di erent Port by continuously 
pushing               .
NOTE: There are no <OK> or <DONE> commands in the stacking menu. Whichever value—Master or 
Slave—shows up on the MATE screen will be assigned to the chosen Port (and FX) upon leaving that 
screen. It’s important to watch the Port number in the top right corner of each screen to be sure you’ve 
assigned it the desired status.
Systems with two to ten FXs call for OutBack 
Slave Stacking. Press                in the ADV/FX/
STACK screen to change the stack phase from 
Classic Slave to OB Slave L1.
